Abstract: Incentives for implementing new pollution-control technologies are both regulatory and economic. Given considerable regulatory pressure, e.g., the promulgation of a NESHAPS (National Emissions Standard for Hazardous Air Pollutants) for NOx emissions in CY 2000, new de-NOx technologies are being explored. One major reason for this is that conventional de-NOx methods (like wet scrubbers plus Selective Catalytic Reduction -SCR) will not work effectively for the low NO concentrations (e.g., <50 ppm), high exhaust-gas flow rates (- 10(6) Nm(3)/h), and low gas temperatures (near ambient) characteristic of Jet Engine Test Cells (JETCs). Our project is currently evaluating non-thermal plasma (NTP) technologies for treating jet-engine exhaust and other hazardous air pollutants. In this paper, we will present our initial design options for NTP reactor systems for a field-pilot demonstration on small jet engines (e.g., F107 or F112; flow rates ^104) Nm(3)/h). The field-pilot demonstration is necessary to provide further data and operating experience to more fully evaluate economic and performance projections for NTP de-NOx technology and to design larger systems with confidence.
